There are two SAS controller card options for the Sun SPARC Enterprise T5120
and T5220 servers (both options support RAID). The standard option uses the on-board
SAS controller card preinstalled on every server. The second option is a StorageTek
SAS RAID Internal Host Bus Adapter (HBA) PCIe card. The internal cabling of
your server will be different depending on the SAS controller card option you choose.
